[JBoss-user] CMP, multiple workers and shared DB (help me!)

[Raquel V. Lopes]

Hello! I am running xPetStore (that uses CMP) implementation at JBoss 3.0.7. I have multiple workers (JBoss machines) that shares the same database. The database I am using is the Hypersonic that comes with JBoss. I am also using Apache+mod_jk to load balancing requests among the workers. I need to - on the fly - stop some instances of JBoss, and then, start them again. But, when a JBoss instances dies (shutdown on JBoss) all the database is removed and the other instances aren't able to correctly continue to serve client requests. How could I prevent the database to be deleted when one JBoss xpetstore instance is undeployed? Thanks a lot, Raquel
